Work History
Enterprise Messaging & Integration Technical Lead
Crypto.com
02.2025 - Current
- Primary technical point of contact for Kafka and AMQ, owning platform engineering from technical analysis and architecture through hands-on implementation, automation, testing, migration, troubleshooting and production readiness while providing technical leadership, partnering with enterprise architects and application teams and driving successful enterprise messaging adoption.
- Initiated and delivered the enterprise messaging modernization from licensed Red Hat AMQ on physical infrastructure to a distributed Kafka platform after evaluating application messaging patterns, throughput requirements and infrastructure costs; successfully migrated 50+ business-critical messaging flows to improve scalability, throughput, high availability, resiliency and long-term platform sustainability.
- Resolved recurring production stability issues in the legacy AMQ Master-Slave architecture, where high-load conditions and network failures resulted in split-brain scenarios impacting critical applications; migration to Kafka established a highly available distributed messaging architecture while eliminating enterprise licensing costs, physical infrastructure dependency, RHEL migration efforts and AMQ platform upgrade overhead.
- Designed phased migration strategies for applications with multiple producers and consumers using an AMQ–Kafka bridge, facilitating incremental migration while maintaining interoperability and preventing disruption to dependent business services.
- Owned the end -to- end migration lifecycle from solution assessment and strategy through implementation, testing, application cutover, and production readiness, collaborating with development teams to resolve dependencies and ensure successful production adoption.
- Owned the end-to-end design and implementation of the Kafka KRaft platform from scratch, leading requirement gathering, architecture, infrastructure sizing, capacity planning, cluster deployment, testing and production readiness for enterprise messaging workloads.
- Designed and engineered the complete KRaft platform architecture, defining broker/controller topology, partitioning, replication, storage, security and availability strategies based on application throughput, resiliency and future growth requirements.
- Built and automated the entire Kafka platform deployment using Ansible, developing reusable playbooks, templates and operational tooling for platform provisioning, topic lifecycle management, ACL administration and routine cluster operations, significantly reducing manual effort and ensuring consistent deployments.
- Managed the complete operational lifecycle of 12+ Kafka clusters, leading platform validation, performance tuning, resiliency and failover testing while ensuring production readiness, application onboarding and long-term platform stability.
- Served as the primary Kafka SME, partnering with application teams to provide end-to-end technical guidance on producer/consumer integration, topic design, connectivity, security (SSL/ACL), configuration, performance optimization, troubleshooting and production support, ensuring reliable adoption of the enterprise messaging platform.
- Designed and implemented MirrorMaker 2 (MM2) replication architecture supporting disaster recovery and Demo/Live environment flip scenarios across Kafka clusters.
- Configured and validated MM2 connectors, replication policies, topic replication, offset synchronization, and failover workflows, ensuring reliable cross-cluster replication and seamless application continuity during migration and disaster recovery.
- Evaluated multiple replication approaches through POCs and production-like validation, identified cyclic replication challenges and established a scalable, production-ready replication strategy aligned with enterprise DR requirements.
- Automated MM2 deployment and environment-flip activities using Ansible, developing reusable playbooks and configurations to standardize deployments and minimize manual intervention during environment transitions.
- Executed end-to-end replication, failover and environment-flip validation by simulating production scenarios, verifying data consistency, consumer recovery, replication behavior and operational readiness before application cutovers.
- Adopted AI-assisted engineering practices using Claude and Cursor to accelerate platform automation, operational tooling, troubleshooting, documentation and solution development across Kafka and Mirrormaker initiatives.
Senior Messaging Operations Engineer
IG Infotech
01.2022 - 02.2025
- Delivered AMQ infrastructure modernisation from physical to virtual environments, achieving approximately £57K in infrastructure savings while improving GC performance by ~80% and throughput by ~40% through platform optimization.
- Administered and supported enterprise Red Hat ActiveMQ (Artemis) platforms, including Master/Slave and Master/Slave with ZooKeeper quorum deployments, ensuring high availability and reliable messaging across production environments.
- Configured and validated the migration from traditional Master/Slave to Master/Slave with ZooKeeper quorum broker deployments, mitigating split-brain scenarios and improving broker coordination, failover reliability, and production stability.
- Executed AMQ and JDK upgrades, hotfix deployments, compatibility validation, load testing and production rollouts while analysing latency, throughput, GC behaviour, enqueue/dequeue rates and resource utilisation.
- Performed capacity planning, performance tuning and load testing to optimise broker configurations, improve messaging performance and ensure production readiness for business-critical messaging workloads.
- Administered and supported Enterprise Confluent Kafka and Open Source Kafka platforms across on-premises, AWS, GCP and Confluent Cloud, managing Brokers, ZooKeeper, Kafka Connect, Confluent Replicator, Control Center and Schema Registry for enterprise messaging workloads.
- Delivered Kafka, Confluent and JDK upgrades, performing compatibility assessments, performance benchmarking and production rollouts across enterprise messaging environments.
- Implemented Kafka Connect, MirrorMaker and Confluent Replicator to enable secure cross-cluster replication, cloud integration and disaster recovery.
- Migrated Hortonworks Schema Registry (HSR) to Confluent Schema Registry (CSR) and validated Open Source Kafka to Confluent Platform migration through schema compatibility analysis, application validation and production readiness testing.
- Strengthened Kafka platform resiliency and security by implementing rack-aware deployments, replication strategies, SSL/SASL authentication and production best practices, improving availability and eliminating single points of failure.
- Collaborated with application teams to gather messaging requirements and design scalable Kafka solutions, resolving complex producer/consumer and integration issues to ensure performance and reliability.
